[eng] The institutionalisation of political economy, this is, the processes through which political economy turned into a scholarly discipline, has become a field of increasing interest in the realm of the history of economic thought. The analysis of the evolution of these processes has been made through the study of the presence and significance of political economy in some key institutions, considered the pillars of the diffusion of economics in Western societies in the second half of the 19th century and first decades of the 20th: universities, economic associations, economic periodical publications and the national parliaments. This paper presents a comparison between the development of the process of institutionalisation of political economy in Spain and Italy, through the study of the presence of political economy in the aforementioned set of institutions in both countries in the period 1860-1900. Its aim is to assess the existence of a common path in the development of this process in both countries. This would be a starting point in order to test the existence of a model of institutionalisation of economics in this period.
